pdf_page_layout

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries full burden. It mentions the layout options (2-up, 4-up) but fails to disclose important behaviors like handling of odd page counts, page ordering, or whether the original file is modified. The description is minimal beyond the basic operation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with the core purpose. Every word is meaningful with no fluff. The structure makes it quick to parse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the low complexity of the tool (simple N-up layout) and full schema coverage, the description provides adequate context. It could mention that the output is a new file (implied by outputPath) but overall is sufficient for an agent to understand invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents all parameters. The description adds some context (e.g., 'side-by-side', '2x2 grid') that reinforces the schema's enums, but does not provide additional semantic value beyond what the schema already offers.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: arranging multiple PDF pages onto single sheets in N-up layouts (2-up or 4-up). It specifies the verb 'arrange', the resource 'PDF pages onto single sheets', and differentiates from sibling tools like pdf_merge or pdf_split by focusing on page layout rather than merging/splitting.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides context for use: 'useful for printing handouts, saving paper, or creating thumbnail sheets.' It implies a scenario for N-up layouts but does not explicitly state when not to use or name alternatives. The sibling list offers other PDF tools, but no direct contrast is given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
